Also work very well on standard metals steels, RSG, aluminium, high temperature alloy, titanium alloy, non ferrous metals, plastics and wood.

Unique centering point precise drilling without gradient

Areas of use For making holes through alloyed and mild steel, non-ferrous metals, cast steel, cast iron and plastic

Notes - Choose the right lubricant can facilitate cutting or cooling, make cutting easier, and improve dimensional accuracy. Please pay attention to the speed adjustment when using the electric drill. The larger the drilling size, the slower the speed requirement.

Cobalt Material The drill bit for metal is made of high-speed steel with M35 cobalt, provides high hardness(HRC64-HRC66), good toughness, and wear resistance.

A 135-degree split point grinding ensures perfect centring and reduced drilling pressure.

HSS Cobalt Long Series Drill Bits - For drilling particularly tough or hard metal drilling applications such as stainless steel, hardened metal, cast iron, Cr-Ni and special acid resistant steels. Also work very well on standard metals steels, RSG, aluminium, high temperature alloy, titanium alloy, non ferrous metals, plastics and wood.

High Speed Steel Made of HSS cobalt material, the drill bit is hard enough, anti-bending and will not fracture easily. The surface coating can better protect the drill bit sets from corrosion and expand their longlife.

M35 high speed steel with 5 percent cobalt for strength and wear resistance

Precision Ground All HSS drill bits are precision-made with ground flutes and edges for accurate hole drilling from start to finish.

High durability The increased speed of the drill bit means less heat is built up, reducing wear

High Durability Made of tungsten steel material for anti-bending and anti-fracture durability, ensuring long-lasting use. Black & Gold Oxide Finish enhances lubrication and corrosion resistance, improving the overall performance of the drill bits.

Fits all brands

Exceptional Durability Crafted with 5% Cobalt M35 HSS-CO material, ensuring outstanding wear resistance for long-term stability and reliability in high-intensity work.
